一：问题

1：比如这是接收到的外部参数为json：{\"4\":{\"data":\"leyangjun-private/1660875949898375470-418163.jpg\"}}

2：然后使用json.Unmarshal 反序列操作，会返回：“invalid character '\\\\' looking for beginning of object key string“ 的错误

二：解决

jsonStr, jErr := strconv.Unquote("\"" + jsonStr + "\"")     //直接把json字符串用Unquote处理一次即可

Unquote函数描述：
// Unquote interprets s as a single-quoted, double-quoted,
// or backquoted Go string literal, returning the string value
// that s quotes.  (If s is single-quoted, it would be a Go
// character literal; Unquote returns the corresponding
// one-character string.)
